Functionalization of fullerene at room temperature: toward new carbon vectors with improved physicochemical propertiesElectronic supplementary information (ESI) available. See DOI: 10.1039/c6ra23419d

In this work, fullerene has been functionalized with cyanuric chloride at room temperature by a nitrene mediated [2 + 1] cycloaddition reaction. The adduct after functionalization is inherently in the form of azafulleroid and shows broad UV absorption in the wavelength range of 200-800 nm, as well as photothermal conversion and fluorescence with a high quantum yield.
